Hopefully that's the last time you will need shock tactics, though!
Good tip! I suppose the other consideration is tightening the tool...

Even if you want to zero on an edge, and are going to be using metric coordinates, say, you can pick up the edge with the wiggler, then set the coordinates to half the wiggler diameter (0.25" in my case), and zero is on the edge. Then switch to mm and away you go! So much easier than dials...
Ah I see - Sounds very useful, hopefully my DRO has a similar function. Of to search the internet for a manual!

I don't suppose you know what is missing from the side of the mill do you? Does your Warco have a similar hole on the side?
